LMX2572 is an RF frequency source module based on the TI LMX2572 wideband frequency synthesizer, featuring ultra-wideband coverage and low phase noise. The module uses a differential dual-end four-channel RF coupled output design, and integrates advanced features such as phase synchronization, frequency ramp, direct digital FSK modulation, and JESD204B SYSREF generation. It can serve as a local oscillator signal source or reference clock, flexibly used in R&D debugging and system integration scenarios. The module can be used for local oscillator signal generation in radar and satellite communication systems, low-jitter clock sources for high-speed data converters (ADC/DAC), frequency synthesis for MIMO and proprietary wireless communication systems, as well as R&D and verification scenarios requiring wideband, low phase noise frequency excitation such as test and measurement instruments, DMR digital radio, and wireless microphones.
Output frequency range: 12.5 MHz–6.4 GHz Phase noise (chip level): -106 dBc/Hz @ 100 kHz offset, 6.4 GHz carrier Output channels: differential A/B four-channel (SMA interface) Module power: +5 V, operating current < 200 mA Data interface: H-2X5P (directly connectable to USB2ANY for programming) Module dimensions: 7.5 × 5.5 × 1 cm
